This week the Sierra Club’s Big Picture Campaign won its biggest victory yet when the Obama Administration finalized the Endangerment Finding, giving the EPA the authority to fight global warming emissions.

Thanks to the tens of thousands of Sierra Club activists like you who sent messages to the EPA, attended rallies coast to coast, and testified at public hearings the EPA finally has the power to fight climate change – now it’s time to use it.

Did you know that only a handful of huge factories emit over half of all global warming pollution in the US? It’s time to make these Big Polluters clean up their act, and that’s exactly what the EPA is proposing to do with the new authority granted by the Endangerment Finding.

Big Oil and Coal are already fighting the EPA’s plan to use the Endangerment Finding to hold them responsible. We need your help to show that Americans are tired of Big Polluters putting us all at risk.

Right now, the National Wildlife Federation has a delegation at the global climate summit in Copenhagen, Denmark to speak up for a climate treaty that protects our natural resources and reduces global warming pollution.

With all the “Ho Ho Ho” of the holiday season upon us, here’s a simple way to do something green instead of killing a pine tree for Christmas.

The green way is to rent a live Christmas tree for the holidays and then have the tree returned to the environment, alive.

And, the glory of this approach is that you don’t have to do any of the work, you just order the tree and it arrives potted.

After the holidays, the company picks up the tree and bingo, a green Christmas. Your company joins the ranks of those adopting a green office strategy.

Two companies, Evergrow Christmas Trees Co. and Carbonsync Christmas offer the live-tree rental service for about $100 a tree. The trees are returned to nurseries until needed next year. Normally, a tree that takes six to twelve years to grow into a Christmas tree is turned into mulch after a single season.

By renting a live tree and returning it to the nursery, the trees continue to soak up carbon dioxide, so the rental service is yet another way to minimize emissions that create climate change.

In other green Christmas developments, how about running the lights on your tree in a carbon-free manner?

Today, news leaked [1] that the U.S., Denmark, and a cabal of other wealthy nations that are among the world’s biggest polluters have, in secret back-room dealings, produced an alternative draft text to the one that’s officially under negotiation.

This secret alternative — known as the “Danish text” — would let rich countries shirk their responsibilities to lead the way in cutting greenhouse gas emissions and force poor countries to bear an unfair burden of the costs of keeping the climate stable.

The United States must reject this secret text and renounce the type of underhand wheelings and dealings that have produced it. We’ve already filled the atmosphere with far more than our fair share of greenhouse gas pollution. The climate negotiations should not be about helping the U.S. save face, they should be about spurring effective global cooperative to solve global warming.
